Constructor Details

#initialize(options = {}, &block) ⇒ Arguments

Initialize an Arguments

Parameters:

  • options (Hash) (defaults to: {})

Options Hash (options):

  • :required (Array[String])

    arguments that must be present before request is fired

  • :api (Github::API)

    the reference to the current api
